Answer: 13

Step-by-step explanation:

In order to solve this equation you need to replace x with 9.

2/3 x 9 + 7=

6 + 7=

I need help with this
Misha Larkins [42]

Answer:

(-3 , 0)

Step-by-step explanation:

The x-intercept is the point on which lies on the x-axis, so when the y is equal to 0.

They y-value can be seen as gaining 16 whole numbers every time the x gains 3.

1. Add intervals of +16 to the y-value (from -32) and intervals of +3 to the x-value (from -9) until the y-value equals 0.

Show:

(-9+3 , -32+16) = (-6 , -16)

(-6+3 , -16+16) = (-3 , 0)

The y-value in the end, is 0 with a x-value of -3.

Is the answer to this question 4.5
Novay_Z [31]

Answer:

x = 30

Step-by-step explanation:

m<E = [m(arc)AD - m(arc)BC]/2

50 = (130 - x)/2

100 = 130 - x

-x = -30

x = 30

Evaluate the Riemann sum for f(x) = 3x − 1, −6 ≤ x ≤ 4, with five subintervals, taking the sample points to be right endpoints.
Verdich [7]

Answer:

The Riemann sum equals -10.

Step-by-step explanation:

The right Riemann Sum uses the right endpoints of a sub-interval:

\int_{a}^{b}f(x)dx\approx\Delta{x}\left(f(x_1)+f(x_2)+f(x_3)+...+f(x_{n-1})+f(x_{n})\right)

where

\Delta{x}=\frac{b-a}{n}

To find the Riemann sum for \int\limits^{4}_{-6} {3x-1} \, dx with n = 5 rectangles, using right endpoints you must:

We know that a = -6, b = 4 and n = 5, so

\Delta{x}=\frac{4-\left(-6\right)}{5}=2

We need to divide the interval −6 ≤ x ≤ 4 into n = 5 sub-intervals of length \Delta{x}=2

a=\left[-6, -4\right], \left[-4, -2\right], \left[-2, 0\right], \left[0, 2\right], \left[2, 4\right]=b

Now, we just evaluate the function at the right endpoints:

f\left(x_{1}\right)=f\left(-4\right)=-13=-13

f\left(x_{2}\right)=f\left(-2\right)=-7=-7

f\left(x_{3}\right)=f\left(0\right)=-1=-1

f\left(x_{4}\right)=f\left(2\right)=5=5

f\left(x_{5}\right)=f(b)=f\left(4\right)=11=11

Finally, just sum up the above values and multiply by 2

2(-13-7-1+5+11)=-10

The Riemann sum equals -10

David completed 12 math problems in 6 minutes. At this rate, how long will it take him to complete 50 math problems ? P
Agata [3.3K]

Answer:

25 minutes...

Step-by-step explanation:

This is because if he can complete 12 math problems in 6 minutes when u simplify that u get 2 problems done per minute so that would make 50 problems done in 25 minutes
